IMPROVEMENT IN CLAMPS FOR STOPPING LEAKS IN HOSE-PIPE-S.

Specification forming part of Letters Patent No. 42.735, dated May 10,-1864-.

To aZZ'wwm it may concern.'

Be it known that I, OIIEIs'rIAN RUBsAM, of Newark, in the count-y ofEssex and State of New Jersey, have invented a new and Improved Clampfor Stopping Leaks in Hose; andl do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe accom panying drawings, forming a part of this 'specilcatiom inFigure l represents a plan or top view ot' greatly dii'ering in size thewidth of the canyasorother'material has to be increased or decreasedaccording to circumstances, but twp orthree clamps of different sizeswill be salcient to meet all contingencies.

To the ends of the canvas or leather A- two strips, B, of metal areIirmly secured by means of' rivets or in any other desirable manner,`and these pieces oi' metal are provided with lugs a, one of which isprovided a with a screwthread to lit to a screw, b, and the other with ahole through which said screw passes freely. If a leak occurs in a hosethe screws b are taken out, the clamp is placed on the leak,

and by reinserting the screws itfis drawn up tight, so that no water canfind. its way out between the hose and clamp, and for all practical`purposes thc hose is rendered just as good as new.

For the body of the clamp I prefer canvas to leather or other material,because the canvas, onbeing attached to a leak when it becomes wet,shrinks and draws np tighter and tighter to the circumference of thehose, whereas leather, on becoming wet, stretches, and it' not tightenedup repeatedly, allows the water to leak out at the ends.

With this clamp a leak in a hose extending twothirds round, or more, canbe readily stopped, and the delay caused by the operation of attachingthe clamps is so small that the hose can be used almost withoutinterruption. It is only necessary to stop the stream for a few minutes,and it a hose burst while playing on a tire, the fire is not permittedto make great headway while the leak is being ent, as an improvedarticleot' manufacture- A leak-clampi'or hose-pipes, composed of thecanvas or fabric A, with attached metallic strips B and clampingscrewsb, made and operating as herein shown and described.
